Without intending to be morbid, having watched many RNZAF UH-1Hs as a lad, and twice riding in one as a pax in the outward facing transmission tunnel seat - am curious.
How does a main rotor separation sequence on a UH-1 end up with blade going through cabin?
Each blade is ~25 feet long - and the mast anchors to the transmission at the rear of the cabin.
I would have thought on separation the rotor's inertia would have meant it continued `flying' and the fuse just dropped.
Does this just happen if you are in forward flight at the time - mast snaps - airload on disc causes it to rapidly pitch extremely forward, at the same time as the fuselage momentum continues through the blade arc?
Forgive the naive question - I am just a humble plank driver...
